Subject: [PATCH v3 32/31] edac: restore mce.h file
Trace doesn't like to have the same trace file included into
two different places. I only noticed it when compiling the
entire tree again on a different machine.
Partially reverts commit 4eb2a29419c1fefd76c8dbcd308b84a4b52faf4d
I'll likely work on another approach, as keeping the mce_record
on a different place than the other *mce traces don't seem right,
but, for now, let's just take the shortest way.
